Hermitian quadratic eigenvalue problems of restricted rank
(1993)
we consider a quadratic eigenvalue problem such that the second order term is a Hermitian
matrix of rank r, the linear term is the identity matrix, and the constant term is an arbitrary
Hermitian matrix A E cnn. Of the ...
Uniform stability of the ball with respect to the first Dirichlet and Neumann infinity-eigenvalues
(Texas State University, Department of Mathematics, 2018-01)
In this note we analyze how perturbations of a ball Br ⊂ Rn behaves in terms of their first (non-trivial) Neumann and Dirichlet ∞−eigenvalues when a volume constraint Ln(Ω) = Ln(Br) is imposed. Our main result states that ...
Eigenvalue homogenisation problem with indefinite weights
(Australian Mathematics Publ Assoc Inc, 2016-02)
In this work we study the homogenisation problem for nonlinear elliptic equations involving p-Laplaciantype operators with sign-changing weights. We study the asymptotic behaviour of variational eigenvalues which consist ...
An inequality for eigenvalues of quasilinear problems with monotonic weights
(Pergamon-Elsevier Science Ltd, 2010-11)
In this work we extend an inequality of Nehari to the eigenvalues of weighted quasilinear problems involving the p-Laplacian when the weight is a monotonic function. We apply it to different eigenvalue problems.
The eigenvalue problem for quasilinear elliptic operators with general growth
(Pergamon-elsevier Science LtdOxfordInglaterra, 2012)
An optimization problem for the first weighted eigenvalue problem plus a potential
(American Mathematical Society, 2010-10)
In this paper, we study the problem of minimizing the first eigenvalue of the p-Laplacian plus a potential with weights when the potential and the weight are allowed to vary in the class of rearrangements of a given fixed ...
Convergence rate for some quasilinear eigenvalues homogenization problems
(Elsevier Inc, 2015-03)
In this work we study the homogenization problem for (nonlinear) eigenvalues of quasilinear elliptic operators. We prove convergence of the first and second eigenvalues and, in the case where the operator is independent ...
